That's what Pink is about to do, however, as she revealed that her kids, 6-year-old Willow and 1-year-old Jameson, got her sick ahead of her big performance.

"Trying to practice the flu away," she captioned an Instagram photo of herself singing at U.S. Bank Stadium in Minneapolis, Minnesota. "I’ve been waiting to sing this song since 1991 when I saw my idol, Whitney Houston, own this song. And now, my chance has finally come."

"It just so happens that this chance comes when I have two small Petri dish kids who literally cough INTO MY MOUTH and rub their snot on my cheek. You can’t write this stuff I swear! And here we are," Pink continued. "I’ve arrived at another one of my dreams which is slowly becoming a sort of nightmare."

"I will tell you, this is one of the biggest honors of my life, singing this song in front of my family, my military family, my dad and brother and step mama and family and the world. And the EAGLES!?!?! I promise I will do my best, as I always do," she concluded. "As far as the gremlins that got me into this mess, you can cough at me for the rest of your lives. If it’s a contest, babies, you win. #spreadthelove #spreadthegerms #pleasegivememyvoiceback #ificansingimgonnakillit."

While Pink will sing "The Star Spangled Banner" before The New England Patriots and the Philadelphia Eagles face off on Sunday, Justin Timberlake will be taking the stage for the halftime show.

"I think I'm just excited," he told reporters on Thursday. "I'm excited to be on this stage once again and at this point in my life. It's just a great opportunity."
